• Vehicle insurance companies demanded in the 90’s an effective technical protection against car theft to be developed by the car manufactures. A primary requirement of the insurance companies was that the anti-theft system should activate itself automatically. Therefore, the car manufacturers developed the self-activating immobilizer system as an electronic anti-theft device. It prevents an engine start with an ignition key unknown to the immobilizer system. This means that the immobilizer function is only deactivated when the ignition is switched on with a registered key and activated automatically when the ignition is switched off.
